SNAP-HOOK.

PECIFICATION forming part of Letters Patent No. 447,567, dated March 3,1891. Application filed January 5, 1891. Serial No. 376,735- (No model.)

To all whom it may concern:

Be it known that I, GEORGE M. HUBBARD, of New Haven, in the county ofNew Haven and State of Connecticut, have invented a new Improvement inSnap-Hooks,- and I do hereby declare the following, when taken inconnection with accompanying drawings and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part of this specification, andrepresent, in.*

Figure 1, a side view of the hook completed; Fig. 2, a top view of thesame; Fig. 3, a longitudinal central sectional view; Fig. 4:, atransverse section on line 00 0c of Fig. 1; Fig. 5, a transverse sectionon line w :0 of Fig. 3; Fig. 6, a perspective view of the cap detached;Fig. 7, a perspective view of the body, hook, and loop with the cap andbolt removed; Figs. 8, 9, 1O, 11, and 12, modifications.

This'invention relates to an improvement in the construction ofsnap-hooks for which Letters Patent of the United States No. 347,108were granted to me August 10, 1886.

The class of hooks to which the invention particularly relates is thatin which the body is made tubular, so as to form a barrel withinwhichalongitudinally-slidingboltisarranged, with a spring to throw thebolt forward into engagement with the end of the hook which.

is formed on the body, the barrel being constructed with a longitudinalslot, through which a projection from the bolt extends, terminating uponthe outside in a thumb-piece for the convenient manipulation of thebolt.

In my previous invention the body is constructed with a loop at one endand a hook at the opposite end, the body being substantially flat uponits upper side, combined with a cap constructed with a longitudinalrecess upon its under side corresponding to the bolt, the recess openingforward toward the end of thehook, and theslotformed in theforward endof the cap, the cap being secured to the body so as to inclose the boltand spring and permit the bolt to slide freely backward and forward.

My present invention has for its object the construction of a cap andits attachment to the body so as to make a firm connection between thebody and cap, and yet give to the hook a neat and finished appearance;and the invention consists in the construction as hereinafter described,and particularly recited in the thickness of the body corresponds sub-.

stantially to the diameter of the bolt.

F represents the cap. This is made of inverted-U shape in transversesection, so as to form two checks to a, one on each side, as seen inFig. 6, the bend of the cap corresponding to the shape of the bolt E, asdid the cap in my previous patent; but in this case the cheeks aredistant from each other corresponding to the thickness of the body, andso as to embrace the two sides of the body, the cheeks extendingrearward substantially to the loop and conforming in shape substantiallyto the shape of the body, and so that the cheeks may set down over eachside of the body, as seen in Figs. 1 and 4. The cap at its forward endis constructed with a longitudinal slot G, through which the thumb-pieceH of the bolt may pass, as in my previous patent. The rear end of thecap is closed, so as to form a chamber forthe spring I between the endof the bolt and the end of the cap, as seen in Fig. 3. The rear end ofthe cap is cast with a projecting stud J from its under side, and thebody is formed with a correspondin g hole K, and so that, the cap beingset upon the body as seen in Fig. 4.,the cheeks will extend down eachside and so as to inolose that portion of the body, while the stud Jwill pass through the hole K at the rear end to be riveteddown upon thereverse side, as seen in Fig. 5, which forms a firm security for thatend of the cap.

'lransversely through the two cheeks and the body at the forward end arivet L is introduced, which firmly unites the cap with the body. Underthis construction the cheeks inclose and cover the sides of the body, soas to give a neat and finished appearance, and the union between the twoparts is made so firm as to prevent possible separation.

The rear end of the cap may be constructed with a hook I) at the rearend, and so that instead of being riveted, as first described, it maypass through the opening or hole in the body and hook thereon, asclearly seen in Fig. 8, so as to hold substantially as firm as whenriveted, as in the first illustration; or the cap may be constructedwith a hook (1 upon each side, which will hook under the forward side ofthe loop, as seen in Figs. 9 and 10; or the cap may be constructed withtwo rivets, one on each side at the rear, and the body withcorresponding holes, as represented in Figs. 11 and 12. In either casethe cap is constructed with the same checks to inclose the sides of thebody.

From the foregoing it will be understood that I claim nothing shown ordescribed in my before-mentioned patent; but

hat I do claim as an improvement upon the said patent is A snap-hookconsisting of a body A, constructed with a hook B at one end and a loopor attaching device at the opposite end, the thickness of the bodycorresponding substantially to the body of the bolt, combined with a capF, of inverted-U shape, the legs of the U forming cheeks a a distantfrom each other corresponding to the thickness of the bodyand so that,the cap being set over the body, the said cheeks will embrace the twosides of the body from the forward end of the cap to the loop and formabolt and spring chamber between the said cap and body, the capconstructed with a longitudinal slot G at its forward end andconstructed at its rear end with a projection adapted to engage with thebody at the rear end, a bolt and spring arranged in the said chamberbetween the body and cap, and a rivet through the cheeks and body,substantially as described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

GEORGE M. HUBBARD.
